Is The 515 Kit Worth It

[SIRUS0331]

JUST WONDERING IF ANYBODY HAS PURCHASED THE 515 KIT FROM DUNCAN AND IF IT IS REALLY WORTH SPENDING THE 3500 BUCKS

The only one I know of yet is on Loren's personal 450. I didn't get a chance to ride it yet.

If it runs better than the 480, then damn. That motor really impressed me.
